CARD-BOARD-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 243,068, dated June 21,l 1881.

Application filed January 29, 1881. (No model.)

To all whom it may concern Be it known that I, PHILIPP BAKE, of the city of Hoboken, county of Hudson, andY State of New Jersey, have invented an Improved Gard-Cutting Machine, of which the following is a specification.

Figure lis a plan or top view of my improved card-cuttin g machine. Fig. 2 is an end view of the same, and Fig. 3 is a longitudinal vertical section thereof.

This invention relates to a new machine for cutting visiting-cards and the like from strips of bristol-board or card-board, and has for its object to make the feeding ot' the paper and the actuating of all the mechanism as nearly automatic as possible, also to insure the cutting of the cards at the proper places, and to prevent unnecessary waste. i

The boards from which cards are usually cut come from the mills in Ycertain lengths, and are then out up into strips, each strip having the length of the card-board. In cutting from the strip cards of certain sizes there is always a little waste. There is more or less waste, according to the different sizes of the cards cut from the strip; and one feature of my inven tion consists in the employment of a gage, which is adjustable, and by means of which the necessary waste and no more is cut from the strip, whereas without such a gage much greater waste is frequently occasioned.

My invention consists, also, in new mechanism for feeding the strip of card-board, in new adjusting mechanism for regulating the stroke of the feeding mechanism, and in the new combination of all the parts with each other, all as hereinafter more fully described.

In the accompanying drawings, the letter A represents the frame of m-y machine. This frame supports atable, B, upon which the strip ot' card-board c to be cut into cards is placed. The table B may be rigidly fastened upon the frame A; but I prefer to make it adjustable lengthwise, so as to regulateits position in accordance with the length of card to be cut; and to this end the table is provided with downwardlyprojectin g loops a, which embrace longitudinal horizontal rails b of the frame A, and which can be clamped fast each by means of a suitable set-screw, d. The table A, which is shown in top view in-Fig.1, has on one side,

on top, a guiding gage-piece, e, which can be laterally adjusted, and opposite the outer part of thesame, also on top, another laterally-adjustable gage-piece, f. The gage f, which can be set at the proper distance from the gage e by means of a set-screw, g, has a spring facepiece, h, which is the gage proper for the strip C of card-board. This face-piece his grooved, by'preference, to receive the edge of the strip C, and is held against the strip by little springs t', which will yield in case the strip G should not be of equal width throughout, and still hold the gage parallel to the edge ot' the sheet and opposite gage; for it frequently happens that in machinery for cutting the card-board into strips the latter are not made with precisely straight edges, and to guard against interruption of the work in case of a slight unevenness of edge this spring-gage 7L has been devised. It slides on pins j, that projectfrom the main barf ot' said gage.

Directly opposite tothe inner part of the gage f is another laterally-adjustable grooved gage, D, which carries on its face the longitudinally-adjustable gage-piece E. The gagepiece E has pointer portion l, which can be moved over a scale on the gage D, as shown in Fig. l. The outer end ofthe gage E has a hook or marked portion, m, which, by its position, determines the extent of the first introduction of the strip to be cut into cards in the machine. In other words, when the strip is tirst introduced its outer or front edge or end is brought in line with the marked portion m of the longitudinally-adjustable gage E, the said gage being lirst set with reference to the scale, so as to be in a position which will allow that strip of particular length to be most profitably divided into cards of the desired extent without causing any more waste than is absolutely nccessary-that is to say, without causing any single card to be wasted in the strip. The table B also carries a springclamp, F, which presses upon the strip C, a1- lowing it to be moved forward or pulled outward toward the knife, but preventing it from being pulled backward.

The front end of the machine carries the swinging knife G, which is held up by means of a powerful spring, H,'that connects witha rod, I, which is joined by a link,J, to the knife IOC G, as clearly shown in Fig. 2. At the prop'er period a cam, a, on a shaft, L, pressing upon the rod I, causes the knife to descend and to ont a card off the strip C of card-board. The knife Gr moves along a plate, o,.which is rigid on the frame A, and, together with said knife, constitutes a species of shears by which the card is cut but above the transverse plate o is a cross-bar, p, which, with o, constitutes the front clamp for the strip. This cross-bar p, whenever the knife is down, is pressed down upon the strip O by means of a spring, q, of

less power than the spring H; but when the knife Gr is raised, asin Fig. 2, its blade strikes a projecting hook, r, of the cross-bar p, and lifts the cross-bar, so as to release the front end of the strip G and allow it to be fed forwardwhile the knife is up. As soon as the knife descends and moves away from the hook r the spring q reasserts its power and presses the bar p tightly upon the strip G, so as to render the latter immovable during the actual process of cutting. l

Between the parts just described-that is to say, between the clamp o p and the front end of the table-is the sliding` feed-piece N, which is a slide carried on the rods b by means ofa pitman, s, and crank-wheel t. The wheel tis attached to a shaft, M, to which rotary motion is imparted by suitable mechanism, and which also gears into the shaft L, that has been heretofore mentioned. As the shaft M is revolved, and with it the wheel t, the pitman s moves the slide N back and forth on the rails b. The slide N carries a spring-clamp, w, above a supporting-plate, fr, as shown. When the slide N is moved backward toward the table this clamp w is loose on the strip C, which passes between it and the plate fr; but when it is moved forward toward the knife it takes hold of the strip C and moves it along through when the knife reascends and opens the clamp- I op, allowing the next forward stroke of the feed-piece Nto move another given portion of the strip C through the clamp 019,850. It will thus be seen that the feed-piece N, by moving from the clamp F, with which it may come into almost positive contact, to the clamp o p, with Which'it may also come into almost positive contact, is enabled to feed the very last rem nant of the strip C to the cutting apparatus.

If desired, the clamp F may be omitted; but in this case the mechanism for moving the slide N and for raising the knife Gshould be so carefully gaged that the clamp o p will not be opened until the full backward stroke of the. feed-piece N has been attained, whereas with the additional clamp F the strip G will be prevented from moving backward, even if the clamp o p should be open during part of the backward stroke of the feed-piece. The position of the feed-piece during the throw, which is controlled by the crank, can be regulated by making theV pitman or rod s eXtensiblei. e., in two parts, as shown-and allowing it to be lengthened or shortened at will. To this end, for actual use, I also p refer to apply a pointer, a2, to one portion and a scale, b, to the other portion of this extensible rod s, as indicated in Fig. 3, so that the requisite length of rod can be instantly found by reference to the scale for any given size of card. A set screw, d2, serves to clamp the two parts of the rod s together in the desired position. For regulating the stroke of the feed-piece the crank e2 of the wheel t is adjustable in a slot of said wheel, the crank-pin being attached to a nut, which can be controlled by means of a screw,f2. By turning this screw the crank-pin is set nearer to or farther away fromthe center of the wheel t, and the degree vof stroke consequently regulated; and here, also, I prefer to form a pointer on the adjustable crank-piece, as shown at g2 in Fig. 3, and cause the same to move over a scale, h2, which is attached to the wheel t.

For operation the gages e, f, and I) are first set according to the width of the strip to be cut, and the strip is then introduced into the machine until its front end is in line with the marked portion m of the adjustable gageE, said gageE having iirst been properly set with reference to the length ofthe strip and to the size of cards to be cut therefrom. The machine is then set in operation, and the rst piece dctached willv be part of the waste piece necesvsarily lost from the strip, and from that time on the strip will be divided into cards of the given size, one just like the other, the last piece cut being again a waste piece, so that each card is cut by the machineon two of its sides. Whenever a change of size in the length of strip to be cut or of card to be made therefrom is occasioned, the parts are first adjusted corre spondingly. Thus from a strip measuring twenty-two inches in length can be cut eleven cards, each measuring one and seven-eighths, leaving a Waste of one and three-eighths inch for each strip.
